AC-Side Impedance-Based Stability Assessment in Grid-Forming Modular Multilevel Converters
IEEE AccessGrid-forming converters can emulate the behavior of a synchronous generator through frequency droop control. The stability of grid-forming modular multilevel converters can be studied via the impedance-based stability criterion. This paper presents an ac-

Validation Aspects for Grid-Forming Converters Based on System Characteristics and Inertia Impact
Energies, 2023 Grid-forming converters are considered a key technology for electrical grids with a high share of renewable energy. However, there is a lack of a general, robust and verifiable definition of what constitutes this behaviour. Therefore, this paper presents

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Grid‐forming requirements based on stability assessment for 100% converter‐based Irish power system
IET Renewable Power Generation, 2022 The fault response of a 100% converter‐based system can be significantly different to that of a synchronous generator‐based system, considering the lower capacity headroom, but flexible control capability, of power electronic converters.
